Re: POWDER FOR THE 300 RUM?

RL-25 has by far been the best performing powder for my 300 RUM both in accuracy and velocity. I run top loads with awesome accuracy.

I have noticed a bit of differance in loading from lot to lot. I just moniter my velocity and if its lower, I add, if its higher I drop it some. As soon as I make a small adjustment, presto, groups are pefect again.

I have used four lots of powder and each time I get perfect accuracy even though I have to adjust slightly. I have used other powders that no matter what I did, the new lot just would not group despite the old one being excellent.

Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
